Description: Resistors are a good thing, in fact, they’re actually crucial in a lot of circuit designs. The only problem seems to be that resistors disappear into thin air. The only way to be sure that you’re gonna have the resistor you need when you need it is to stock up, and keep them organized. We have just the thing!

Our new branded resistor kit comes with 25 each of 20 different resistor values (including 0Ω links!). All of these resistors are stapled into a tri-fold pack and clearly labeled. The back of the resistor kit even has a resistor color code look-up chart and a table of color codes for the included resistors!

We’d like to give Oomlout credit for coming up with this great idea. Thanks guys!

Values Included:

  • 0Ω, 1.5Ω, 4.7Ω, 10Ω, 47Ω
  • 100Ω, 220Ω, 330Ω, 470Ω, 680Ω
  • 1kΩ, 2.2kΩ, 3.3kΩ, 4.7kΩ, 10kΩ
  • 22kΩ, 47kΩ, 100kΩ, 330kΩ, 1MΩ

Customer Comments

  • I want this, but with capacitors. Please?

    • Double ditto! I just bought the assorted ceramic capacitor bag from RipoffShack, and out of the 100 in the bag, there was not a single one I could use in my project. Plenty of 10pF caps, though.

    • Ditto on the caps!

    • Yes, can we please please please get a capacitor kit?

    • Hmmm / last year / 1

      yes, though ceramic or film caps that would be used in exact values in filters, not electrolytics

  • This is long overdue, but very nicely executed. Kudos.

  • How stiff are the wires on the resistors? I have bought an assortment in the past that had thin wires that were hard to insert into a breadboard without them bending up.

    • In my experience, ¼ watt resistors tend to have leads similar to 22 AWG wire.

      • I have some ¼ watt with a wire thickness of 0.021" and others with a wire thickness of 0.017. One size goes into a breadboard nicely the others don’t

        • Hi,

          I bought this kit a while back. To answer your question, they are not extremely stiff. For direct PCB/proto board soldering, it is good. For breadboard, I find them too maleable for the task. However, my breadboard is really stiff.


  • It would be awesome to get one of these full of ceramic caps!

  • Quite a nice kit, but I believe the 110R resistor is actually 100 ohms… its actually printed as 110 on the front cover but 100 inside the cover.

  • mentioned the 0 Ohm resistors to my brother in law (masters in EE) says they use them in circuit design on PCBs just in case your calculations are wrong and a specific area might need more resistance. Still I think whats wrong with a wire instead but hey I don’t have a masters in Electrical Engineering.

    • “A zero-ohm link or zero-ohm resistor is a wire link used to connect traces on a printed circuit board that is packaged in the same format as a resistor. This format allows it to be placed on the circuit board using same automated equipment used to place other resistors instead of requiring a separate machine to install a jumper or other wire. Zero-ohm resistors may be packaged like cylindrical resistors, or like surface-mount resistors.”

      from wikipedia… used so that they dont need a different machine for jumpers.

      • Yeah I’ve been thinking about this for a while and having 0 Ohm resistors at your disposal would make PCB design easier. Especially for the layperson whom can probably only manage a 2 sided PCB.

    • Hmmm / last year / 1

      it’s identical to a wire, but with the same body as a resistor so it can be grabbed by a machine. there’s no reason to include them in this kit meant for hobbyists. just use a wire.

  • I want a capacitor kit!

  • Hmmm / last year / 2

    “25 each”? Should be a lot more 10 kΩ and 100 kΩ than other values, since you use those a lot more.

  • 0 ohm resistors? I’ve got spools of those and they’ve even got insulation on the outside.

  • When will they be back in stock?

  • Any Chance that you will come out with a ½ Watt resistor kit? For those of us who use bulkier resistors due to… being prone to lighting things on fire…. :/

  • I would pay for a bigger kit if it comes in a great storage unit clearly labeled like your inventors kit.

  • Radio Shack part number 271-312 is a resistor kit with more values. There are more of the more-popular values. It’s pretty rare for Radio Shack to do better than SparkFun, but this is one such case.

  • Great idea but not that useful due to limited selection of values. I’d prefer, say, 10 pcs of 2.5X more values. Or just a bigger kit.

    Also, you need to specify the tolerance.

  • I would rather see a kit with 10 each with 40 different values and or 5 each 80 - 1% would be nice too. AND a good Capasitor already mentioned.. Thanks, Terry

  • Why 4.7, 47,470, 4.7k and 47k? Why not 5, 50, 500, 5k and 50k? What I need is 60k for a sensor. So that means I have to use a 47k, 1k, 1k, 1k, and a 10k to get there. So it can be done, it just looks unpleasant. Or if I was smarter I could put resistors in parallel. Other site have the multiples of 47 resistors as well. I was wondering what they are used for. Maybe they went in line with a variable resistor for adjustment?

    • Good question. 47 is a standard resistor value. Why is it standard? This site has a good explanation.

      Why not sell a kit with the E24 series instead of the E6? My guess is cost.

      Kits get you in the ballpark while experimenting but if you need something precise, it is better to order the part specifically. Also, ask yourself how precise does it need to be for what you’re doing. With these resistors the value could be off ±5%. In your example, you may not even need a couple of the 1Ks. Or you may need more.

  • Could you tell me where this is made from?

  • OMG these little resistors are carbon, and the values are horrible, I can’t believe my friend wants this as a gift. I’m going to have to show him what good components are; some men have to just keep being taught how to use their equiptment

  • This is a fantastic idea, well executed. So much better than my old system of keep these organized. Thank you Spark Fun!

  • What’s the tolerance on these resistors in this pack?

  • SMD version please!

  • Thanks did not see that.

  • When will it be back in stock.

    • For products that are out of stock, SFE tries to give an estimate for new stock on the right hand side of the product page. Currently (2014/01/24) it reads: “We have a purchase for 2000 units. We expect some of these to arrive next on Feb 2, 2014.” I do stress that this is an estimate, however, as logistical issues can always rear their head.

  • What is the pin spacing on these? 100mil, 200mil,300mil,400mil? this is for designing PCBs and need the correct pin spacing for these….Thanks.

  • An irresistible addition to anyone starting out in electronics.

    Color codes in ACTUAL color is a nice touch! I will eventually cut that out and save it when I move my small components and datasheets to a binder (baseball card storer + small baggies).

    I tried putting these resistors in my stiffest breadboard and had with no problem at all! My loosest breadboard holds them pretty good as well.

  • Can we have a PDF of the chart on the back? The sticker is great, but the color version is much more effective.

  • can we get the old unbranded kit back? this kit is way short on values! Also do we really need to pay for 0Ω resistors as part of the kit? I’d call that wire! (unless by some stretch of physics you have found a way for these to really be 0Ω±5% then maybe you could auction them along with your nobel prize!)

  • Is there an SMD version?

  • If only it had some median resistor sizes… Never know when you will need a 12 ohm resistor… Awesome set of resistors for LED noobs to play with…

    • Keep in mind these are 5% tolerance, so if 2 ohms makes a difference in your circuit you should probably be looking for the blue guys…

    • A 1.5 and a 10 in series get you pretty close…

  • Is there any diference between 1/4W and 1/6th Watt PTH at Resistor 330 Ohm 1/6th Watt PTH.

  • I love it!

  • any idea when this is coming back in stock?

    • I have an order with this backordered and was told they’ll have it in stock in the “[n]ext couple of weeks”.

  • Might wanna add “carbon film” and their tolerance to the description, so we don’t have to squint at the picture. ;)

  • Been waiting for something like this! Picked one up.

  • Are these all 5%?

    • Apart from the 0 Ohm resistors, yes. If you look closely at the packaging, you can see the +- 5%. The 0 Ohm resistors are of course +- Infinite % :-)

  • Zero ohm resistors? really? Okay, I can see a use, but I’d really just use a piece of wire, rather than pay for a resistor.

    • Wire looks shoddy. When I open something up from china and see wire jumpers, I am immediately disappointed. But 0Ω resistors look good!

      • I just busted open my old alarm clock and there was wire jumpers all over the place. I have to admit, I was rather disappointed. However I did salvage all kinds of neat parts. I am definitely picking up one of these sweet kits.

        • This kit is on its way to my house along with an Arduino Uno R3 and various other sweet parts. Can’t wait for it to arrive.

  • great stocking stuffer.

    Papa Smurf does bring up a good point. Why 0 ohm? Why not use a piece of wire?

    • Although not really relevant here, they are useful in pick and place, where a wire bridge won’t work properly.

  • Wow really, a Zero ohm resistor?!?! Sometimes I wonder about U guy’s (sniffin too much leaded soldor)

    • I am going to build the world’s highest-precision R2R ladder out of several reels of those 0Ω resistors, once I can find some that are exactly twice their value.

    • They actually are pretty common. They are used in pick and place machines as jumpers- I think wire bridges are harder/require more specialized equipment… :)

    • Actually lead-free solder is much worse for you.

    • The only point I can see in these things is that those who are embarrassed about using jumpers can now make connections without tarnishing their project.

      0 Ohm. Really??

      • It’s linked in the product description;

        “This format allows it to be placed on the circuit board using same automated equipment used to place other resistors instead of requiring a separate machine to install a jumper or other wire.”

      • 0 Ohm resistors are very commonly used in professional engineering design. They typically have two purposes - 1) you can change the resistor value later if desired. Or, 2) you can use the location as a machine-populated jumper. Then you can save money manufacturing PCBs by designing a board that does several different things, but some features are only enabled if the assembly specifies including that ‘resistor’.

      • We manufacture thousands and thousands of PCB’s where I work, for alot of large international customers and we use 0 ohm resistors and almost every board that we use. They are very common components actually.

One of the best resistor kits out there

I love the way this kit is packaged, its very easy and efficient to find the resistor you need and just snip it out of the tape. Has all of the common resistor sizes and its fairly cheap compared to a lot of kits.

Quality Kit of resistors

This kit is exactly as described; LOTS of resistors. I like how it folds out, and It really is nice to know that I have so may resistors to choose from. I have this nagging feeling though that I’m going to run out of a specific resistor one day and be shocked.

A Mandatory Part of Anyone's Electrical Toolbox

The description for this product is pretty spot on. Many circuits will need resistors and this kit has such a variety, you likely won’t need to worry about whether or not you have the right resistor. The little book they come in is a nice organizer, easy to carry with all resistors neatly sorted and attached on tape rolls. It fit perfectly in my toolbox and I have been the resistor guru among my peers. If you build circuits, or plan to begin building circuits, this product will be as helpful as any breadboard, soldering iron or multimeter. Highly recommended.

Comes very neatly organized and orderly

I’ve ordered large groups of resistors in the past, and they all show up out of order and you have to go through and interpret some chicken scratch they wrote as to what the value was and then hope they sent you all they promised and didn’t forget pr duplicate any. This one comes nice, neat, and organized. Very much worth it.

Better than expected

I needed a few extra resistors that this kit provided that I didn’t already have laying around. The resistors are all pinned inside this kit and it shows you which ones are which value. All of my other resistors are in a binder and split out into different sections and I loved that. Ever since I got this though, I haven’t used the binder at all. Glad I ended up getting this kit.

A Necessity For Any Project

I got one of these for Christmas and I have no complaints except for the fact that the labels on the inside are out of order and I couldn’t find half of the resistors.

Different version of preferred value resistors

Unexpected new values for the breadboard, and hole-through use. These have nice long leads. A version I used to buy was:

30ea. 1K,10K,100K

10ea. 1,10,100,120,150,220,330,470,560,1.5K,2.2k,3.3k,4.7K,15k,22k,47k,220k,470k,1m,10m.

5ea. 2.2,15,22,33,39,47,51,68,82,180,270,390,510,680,1.2k,1.8k,2.7k3k,3.9k,5.1k, 5.6k,6.8k,8.2k,12k,18k,27k,33k,39k,51k,56k,68k,82k,120k,150k, 180k,270k,330k,1.5m,2.2m,3.3m,4.7m

Hope you can use this information.

Great product

The packaging is excellent, keeping all the resistors organized with very clear labeling and resistor code diagrams. Highly recommended resistor kit.

(My only gripe is a pedantic one: the example resistor color code given uses the Latin for “that is” instead of “for example.” Not sure how the editor let that slip…)

Resistor kit

A real time saver. It’s the perfect kit to have in my parts larder. When I need a resistor for what ever I happen to be working on. I just reach for my stock of resistors, pluck out the one(s) I need and keep working.

good for me

i like it
